I've built a board with 6 layers with blind vias, and the stackup is like this:
Top routing/components
Ground
Power1
Power2
Power3
Bottom routing/components
The blind vias run from: top-ground (1-2), top-power1(1-3), top-power2(1-4), top-power3 (1-5), bottom-ground (6-2), bottom-power1(6-3), bottom-power2(6-4).
Problem is, no one seems to be able to fabricate this board. What are the upper limits for the number/types of blind vias for a 6 layer board? Also, would backdrilling be a better (more manufacturable) option?
